Introduction

In today's society, green and low-carbon development has become an important trend: The iron and steel industry is a typical resource- and energy-intensive industry:

A key area for green and low-carbon development: The implementation of green steel product evaluation can effectively promote steel enterprises to carry out green technologies such as energy saving and emission reduction:

Improve the quality level of green steel supply in the market, promote structural optimization and green, low-carbon and high-quality development of the steel industry, and help the steel industry the green transformation of the industry and the early realization of the double carbon target:

This document clarifies the concept of green steel products, aiming at long-process steel products with coking (optional), sintering/pelletizing, ironmaking, steelmaking, and steel rolling Iron production enterprises, with the principle of green high-end leadership, have established a green steel product evaluation index system, and given the evaluation criteria for green steel products:

The aim is to provide a basis for the certification of green steel products and provide technical support for the country to implement green product label certification and green building certification:

support: This document focuses on the evaluation of green steel products of ordinary carbon steel and low alloy steel, other types of steel can also refer to this document evaluate:

Evaluation requirements for green steel products

1 Scope

This document specifies the basic requirements, evaluation methods, evaluation content and evaluation results of green steel product evaluation:
